From a recent action manager refactoring (https://github.com/odoo/odoo/commit/32b8cec5361174c92c45a4975d4e02f1fb448aa2), the attribute 'views' in viewOptions is now structured as follow: viewOptions: { action: { views: [{ viewID: 1, type: 'list', }], } } instead of this: viewOptions: { action: { views: [[1, 'list']], } } The pivot view was not updated correctly, so now it should be correct.
